Large numbers of black, shiny beetles observed on Knapweed within calcareous grassland area, locale known as ‘Grassy Hill. Note how individual beetles have dimpled covering on elytra, pronotum and head region and how elytra do not cover the extent of the abdomen. We observed mostly females in situ but a few males tagging along (Photo 6). Mating pairs observed and several “gravid females with heavily swollen abdomens (Photos 3,4). Would welcome advice / support on this observation.
